Abstract

The successful fracture stimulation and production test of the Amungee NW-1H well placed the Velkerri Shale play and the Beetaloo Sub-basin on Australia’s energy radar. The Velkerri Shale dry gas play is currently Australia’s most promising shale gas prospect; however, it is not the only prospect in the Beetaloo Sub-basin. Four additional potential plays have been identified, each with their own specific risk profile and relative benefits. These are the Velkerri Shale liquids rich gas play, the Kyalla Shale and hybrid liquids rich gas plays, and the Hayfield Sandstone oil/condensate play. Appraising each of these opportunities requires special attention to ensure efficient and appropriate deployment of capital. A framework approach allows for the high-level assessment and comparison of each of the discussed opportunities within the Beetaloo Sub-basin portfolio.

Keywords: Beetaloo, exploration, Hayfield, hydraulic fracture stimulation, Kyalla, liquids, Northern Territory, shale gas, unconventional, Velkerri.

Alexander Côté is the Engineering Subsurface Lead for Growth Assets for Origin Energy in Brisbane, Australia. He is a CFA Charterholder, a Professional Engineer (P.Eng) registered with the Association of Professional Engineers and Geoscientists of Alberta, and he holds a B.A.Sc. with Distinction in Mechanical Engineering from Western University (Canada). Alexander has 10 years of shale and tight gas experience, having worked across many premier unconventional plays in North America and Australia including the Montney, Deep Basin, Marcellus, Eagle Ford, Beetaloo and Cooper during this time. He has developed expertise in unconventional resource exploration, evaluation, and development. Alexander is a member of SPE.
